There's fundamental analysis that takes big economic data and events that can have an impact on economies into account. Then there's technical analysis which is focused on the historical and real-time movement (candlestick) of a currency pair. Which to use depends on what kind of trader you are. Long-term traders tend to use fundamental analysis. Short-term traders tend to focus on technical analysis. It's been a while since I traded forex, but I'm pretty sure these are still the case. Whatever you do, make sure you have a Trading Plan. Otherwise, it's just gambling. hahaha
